How to Speed Up Audio on a PCSX2

Updated July 20, 2017

PCSX2 is a free, open-source PlayStation 2 (PS2) software emulator for Microsoft Windows and Linux operating systems. PCSX2 allows players to play PS2 discs on their computer by utilising the DVD drive. Due to varying computer speeds and graphics card compatibility issues, PCSX2 includes many customisable options and settings to help optimise the emulator's performance. Audio playback can become distorted or slowed down when the audio settings are not properly adjusted. PCSX2 features a simple audio latency slider to generate accurate real-time audio.

Click "Config" in the main PCSX2 tool bar and highlight "Audio (SPU2)."

Select "Plug-in Settings" from the Audio drop-down menu.

Click on the "Synchronizing Mode" selection box within the "Output Settings" section of the "Plug-in Settings" menu and select "TimeStretch."

Click and drag the "Latency" slider all the way to the left, creating a 50 millisecond delay. The "Latency" slider is located below the "Module" selection box in the "Output Settings" section of the "Plug-in Settings" menu.

Click "OK" to save the audio plug-in settings and return to the main PCSX2 menu.


If the audio is still distorted after reducing the latency to 50 milliseconds, increase the latency to 100 milliseconds. Continue to increase the latency by 50 millisecond increments until you are satisfied with the audio output. If you are unable to generate accurate audio after changing the latency settings, you may need to invest in a new sound card for your computer.
